Port, who lost halfback Ryan Burton in the first term to a hamstring injury, was well served by Tom Rockliff, who collected a game-high 41 disposals, Travis Boak (28 possessions) and Sam Powell-Pepper (two goals).

But the Power were never in the hunt early – they were goal-less in the opening quarter and trailed by 11 points at quarter-time.

Adelaide outscored the Power four goals to two in the second stanza, with Lynch booting two – the first from a fortunate holding-the-man free, the second from a clever snap from a tight angle.

The Crows took a 21-point advantage into halftime and booted with four goals to one in the third term.

Adelaide led by 38 points at the last change and when Lynch scored his third goal inside 60 seconds of the final term, his side had a 44-point buffer.

Port then staged a belated rally with five goals in a 16-minute scoring spree to sneak within 12 points.

But Adelaide’s Lynch then sealed the deal with a shrewd pass to his co-captain Taylor Walker (two majors), who goaled to end Port’s challenge.
